Abstract: PURPOSE: A grounding method using a uni-directional characteristic of a diode is provided to prevent a wrong operation of a CPU control box, a frequency vibration of a ground line, a frequency interference between electric equipments, change in characteristic of a communication line, and a noise of an electronic illumination devices, etc. CONSTITUTION: Signal lines of an image and a sound are connected to generate a huge charge potential. When a ground line is connected, a surface current and a potential of an electric equipment are collided, thereby causing a loop phenomenon and a huge frequency. To eliminate bad influence on the electric equipment, a grounding resistance is reduced, and a phase separation and a load separation are performed to make a one-to-one ground line. But this way is difficult to be carried out in fact. Since a grounding effect cannot be achieved due to a surface current generated by a concentration of a building and excessive function of concrete and reinforcing rods as a condenser. Accordingly, when the devised product is used and grounded, a surface current is avoided, and a mutual interference of ground lines are avoided. In consequence, fire probably caused due to discharge of charge potential of each line and leakage is prevented. A wrong operation of the electric equipment is also prevented, thereby extending life.
